摘　　要：为解决106工作面原支护参数下存在的顶板下沉严重、底板底鼓严重、锚杆被拉断以及液压支架破坏严重等问题,在对106工作面顶底板条件分析的基础上,对导致支护能力不足的问题进行分析,并通过对锚杆、锚索等支护参数优化的基础上增加混凝土喷射的强化支护;最后,通过数值模拟分析对优化后的支护效果进行验证,得出优化支护措施的有效性,可提供1 MPa的支护能力。In order to solve the problems such as serious sinking of the top plate,serious bottom drum of the bottom plate,anchor rods being pulled off and serious damage of the hydraulic bracket under the original support parameters of the 106 working face,the problems leading to insuficient support capacity were analyzed on the basis of the analysis of the top and bottom plate conditions of the 106 working face,and the reinforced support of concrete injection was added on the basis of the optimization of the support parameters such as anchor rods and anchor cables through accounting;finally,the The optimized support effect is verified by numerical simulation analysis,and the effectiveness of the optimized support measures is concluded,which can provide a support capacity of 1 MPa.
